B59883C0120A051

Ptc Resettable Fuses Overview

The B59883C0120A051 is a ceramic PTC thermistor from the TDK 883A series, designed for overcurrent protection in leaded disk-style applications. It features a maximum rated voltage of 550V and a hold current (Ih) of 12 mA. The trip current (It) is specified at 24 mA, with a maximum surge current rating of 100 mA. At 25°C, the typical resistance is 1.5 kOhms with a tolerance of ±25%. The component operates within a temperature range of 0°C to 60°C and utilizes a radial, disc package with a 5.00 mm lead spacing.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption upon detection of excessive current flow.
• Functions as a resettable fuse that restores conductivity after fault conditions clear.
• Constructed from ceramic materials suitable for through-hole mounting configurations.

Ptc Resettable Fuses Applications

• Overcurrent protection for low-current electronic circuits
• Thermal management components in industrial electronics
• Safety protection in automotive electronic systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '051' against the manufacturer's latest documentation to confirm packaging type and marking variations. Ensure compatibility with RoHS3 standards if required by the target assembly. Cross-reference the UL certification number for final safety compliance validation before integration into regulated equipment designs.

Ptc Resettable Fuses Selection Notes

Select this component when high-voltage isolation up to 550V is required alongside precise low-current tripping characteristics. The 1.5 kOhms initial resistance suits applications where minimal power dissipation is critical during normal operation. Consider the 0°C to 60°C operating limit to ensure reliability under expected environmental thermal conditions.

Ptc Resettable Fuses Part Context

This part belongs to the EPCOS (TDK Electronics) B59883 series of PTC thermistors. The series is characterized by its use in protecting sensitive circuitry from overcurrent events. The specific model denotes a variant within the 883A family, optimized for radial leaded disk packages commonly used in through-hole PCB assemblies.

Ptc Resettable Fuses Replacement Considerations

Consult official TDK substitution guides for direct equivalents. Verify that any alternative maintains the 550V rating and 12 mA hold current specifications to ensure functional parity in existing designs.
